}
updateQuiz();다음은 문제출력에 대한 정보를 화살표 함수를 이용해 넣어줍니다.
main에서 주석처리 해뒀던 정보들을 여기로 가져와줍니다.
그리고 아래에 점수확인과
style.display를 사용해 설명숨기기를 해줍니다.
정답확인
//정답 확인
const answerQuiz = () => {
const quizChoices = document.querySelectorAll(".quiz__choice");
//사용자가 체크한 정답 == 문제 정답
quizInfo.forEach((question, number) => {
const userSelector = `input[name=choice${number}]:checked`;
const quizSelectorWrap = quizChoices[number];
const userAnswer = (quizSelectorWrap.querySelector(userSelector) || {}).value;
const dogWrap = quizWrap.querySelectorAll(".dog__wrap");
if(userAnswer == question.infoAnswer){
console.log("정답");
dogWrap[number].classList.add("like");
quizScore++;
} else {
console.log("오답");
dogWrap[number].classList.add("dislike");
}
});
//설명 보이기
document.querySelectorAll(".quiz__desc").forEach(el => el.style.display = "block");
//점수 보이기
document.querySelector(".quiz__info").innerHTML = Math.ceil((quizScore / quizInfo.length) * 100) + "점";
}
//정답 클릭
document.querySelector(".quiz__check").addEventListener("click", answerQuiz);마지막으로 정답확인용 코드들을 넣어줍니다.
정답을 클릭하면 사용자가 누른 정답과 지정된 답이 맞는지,
맞으면 정답, 다르면 오답.
설명 보여주고, 점수 보여주기.
